5 Frequently Asked Questions About Civil & Structural Forensics

Civil engineering is the branch of engineering that deals with the design, construction, and maintenance of public works projects, such as bridges, roads, and water supply and treatment systems. Within forensic engineering and analysis, a civil engineer investigates the cause/s of the failure, which can be anything from design deficiencies, construction defects, materials deficiencies, and/or environmental factors.

Structural engineering is the branch of engineering that deals with analyzing and designing structures, including residential, commercial, and industrial structures, bridges, retention walls, etc. to ensure they are safe and stable.

There are many different types of civil engineering projects, including:

-Transportation infrastructure: roads, bridges, railways.

-Water supply and treatment: dams, pipes, reservoirs.

-Environmental engineering: wastewater treatment, air pollution control.

-Real estate development: housing developments, commercial buildings.

There are many types of structural loads, which can be classified into two categories: static and dynamic loads. Static loads are those that remain stationary or move at a relatively slow speed, while dynamic loads are those that move quickly or oscillate back and forth. Some common types of static loads include weight, pressure, and tension, while common types of dynamic loads include wind load, earthquake load, and impact load.

A civil engineer is responsible for the overall design of a civil engineering project, while a structural engineer is responsible for designing the structure within a project. Oftentimes, these two disciplines of engineering will overlap.

Root Cause Analysis Forensic Scientists

The forensic engineer’s mission is to investigate, solve, and explain the most challenging engineering and scientific problems. Forensic engineering is the application of engineering principles and science in investigating the failure of a machine, component, material, structure, system, and more.

While it is easiest to think of our process as ‘reverse engineering’ – using scientific methodology to uncover why something went wrong or stopped working – it is more accurate to say we conduct a root cause analysis.

The Basics of Root Cause Analysis

Root cause analysis is an in-depth investigation of all the potential causes of an incident. When we conduct a root cause analysis, we start with one question: “What step out of the sequence of events would have prevented the incident from occurring if removed?”

This involves gathering extensive data about each potential cause, then evaluating that data to determine which cause would have stopped the incident from occurring.

The Steps of a Root Cause Analysis

While the process of conducting an analysis may differ from case to case depending on the unique circumstances of the situation, every root cause analysis follows these steps:

1. Define the Problem

Defining the problem is not as simple or obvious as it may seem, as it is not uncommon to begin the investigation only to realize that the problem lies in another area. It is crucial, then, to approach every issue with an open mind while laying aside all expectation and confirmation biases.

2. Gather Data

Gathering data means collecting every piece of available information possible. This goes far beyond reviewing raw data, conducting tests, and shifting through evidence, and extends to comprehensive interviews with everyone involved.

3. Find the Cause(s)

After thoroughly defining the problem and reviewing every possible data source, the cause(s) should be evident. They may be technical, human, procedural, or a combination of two or more.

4. Find Solutions

Knowing what caused the event is good for peace of mind and liability issues, but it is not enough in root cause analysis. It is critical to seek solutions, which are classified as corrective (short-term or stop-gap solutions that address the direct cause of the issue) or preventive (long-term resolutions that targets the root cause and prevents it in the future).

5. Develop Strategies to Correct/Prevent

Once the solutions have been identified, it’s time to work with our clients to develop a strategy to prevent the problem from occurring again.

The McDowell Owens Difference

Frequently Asked Questions About Root Cause Analysis

Root cause analysis (RCA) is a problem-solving technique for identifying the root causes (the most basic, fundamental causal factors) behind an accident or problem. By finding and addressing the root causes, businesses and organizations can prevent the issue from recurring in the future. RCA is commonly used in fields like engineering, healthcare, and business/quality management to uncover systemic issues and implement solutions.

The general steps in root cause analysis typically include the following:

- Identify and describe the problem (develop various hypotheses related to the event).

- Gather information about the problem which will often involve creating a timeline of events leading up to the incident to determine if there are any abnormalities that led to the event.

- Analyze the information to identify possible root causes and other causal or contributory factors.

- Based upon the conducted analysis, rule out various hypotheses that do not align with the facts and continue to conduct the analysis until the most likely hypotheses of event is consistent with the facts and root causes.

- Develop and implement solutions to address the root causes.

To identify the most probable root causes of an issue, all potential causes should first be considered. The root causes that are most supported by the available data and analysis are then selected as the most likely explanations for the problem. By thoroughly evaluating the evidence at hand, the underlying factors behind an issue can be determined.

The key is to use a combination of tools to thoroughly analyze all potential aspects of a problem. A systematic methodology is essential for effective root cause analysis. Some common tools and techniques used in root cause analysis are:

5 Whys - Asking "why" 5 times to peel back layers of causes. Helps get to the root of a problem.

Fishbone Diagram - A visual tool that depicts the potential causes of a problem and helps organize potential factors.

Fault Tree Analysis - A top-down logical diagram showing how failures propagate through a system. This helps identify root causes.

Pareto Charts - Bar charts that focus on the vital few causes by showing frequency of problems/defects.

Scatter Diagrams - These diagrams plot data to visualize correlation between two variables and helps identify possible causal relationships.

Control Charts - Charts track process metrics over time to identify special causes of variation, which helps detect root causes of outliers.

Histogram - Histograms visualize the distribution of a process parameter, which can show issues with the process center or variation.

Root Cause Map - Organizes and visually depicts all potential causes and sub-causes, and can help trace back to root causes.

Change Analysis - Compares times when a process worked vs. when it failed to operate effectively.

Barrier Analysis - Identifies barriers that could have prevented a defect, which helps strengthen systems.

5 Frequently Asked Questions About Marine Forensic Engineering Analysis

Marine forensic engineering investigates and analyzes maritime accidents and incidents to determine the causes.

The most common causes of marine accidents include collisions, groundings, fires, and explosions.

One of the most prominent challenges that forensic engineers face when investigating marine accidents is dealing with the often fluid and unstable environment. In addition, depending on the accident, the vessel may have sunk or partially sunk which can alter the condition of key items necessary for conducting a failure analysis.

Forensic engineers use tools and techniques to investigate marine accidents and help pinpoint the initial cause, including photography, 3D scanning, and computer modeling.

Forensic engineering can help to improve safety in the maritime industry by using the knowledge gained in investigating a particular accident to help to identify and correct other similar potential hazards before they cause accidents or injuries.
